A 36 trillion black swan in front of our very eyes

[Austin Wolff]

Can someone explain to me why the national debt (now at $36 trillion) isn't the next black swan issue that will tank the economy? I'm currently having a difficult time imagining the future a decade from now where this issue isn't one of the more important things that needs to be addressed. (Or maybe it is and perhaps I should look into how this will affect my investment portfolio.)
